Topological charge pumping by sliding moiré pattern
Manato Fujimoto, Henri Koschke, Mikito Koshino
We study the adiabatic topological charge pumping driven by interlayer sliding in the moiré superlattices. We show that, when we slide a single layer of the twisted bilayer system…
Continuum model for relaxed twisted bilayer graphenes and moiré electron-phonon interaction
Mikito Koshino, Nguyen N. T. Nam
We construct an analytic continuum model to describe the electronic structure and the electron-phonon interaction in twisted bilayer graphenes with arbitrary lattice deformation. S…
Mapping the twist angle and unconventional Landau levels in magic angle graphene
Aviram Uri, Sameer Grover, Yuan Cao +10
The emergence of flat electronic bands and of the recently discovered strongly correlated and superconducting phases in twisted bilayer graphene crucially depends on the interlayer…
Observation of drastic electronic structure change in one-dimensional moiré crystals
Sihan Zhao, Pilkyung Moon, Yuhei Miyauchi +3
We report the first experimental observation of strong coupling effect in one-dimensional moiré crystals. We study one-dimensional double-wall carbon nanotubes (DWCNTs) in which va…
Diamagnetic levitation and thermal gradient driven motion of graphite
Manato Fujimoto, Mikito Koshino
We theoretically study the diamagnetic levitation and the thermal-driven motion of graphite. Using the quantum-mechanically derived magnetic susceptibility, we compute the equilibr…
Films of rhombohedral graphite as two-dimensional topological semimetals
Sergey Slizovskiy, Edward McCann, Mikito Koshino +1
Topologically non-trivial states characterized by Berry curvature appear in a number of materials ranging from spin-orbit-coupling driven topological insulators to graphene. In mul…
